Water Filtering Tank

Storage tank designed to collect and filter water.

According to the CDC, over 780 million people do not have access to an improved water source (protected from contamination). In an effort to address this problem, our team has ideated a water storage tank and filtration system which can be utilized to filter water from local freshwater sources and water from rain collection. 


The tank will consist of two horizontal compartments. The top chamber will hold dirty water, which will then be filtered and held in the bottom chamber. Users will be able to pour water into the upper compartment from access ports located at the top of the tank. In addition, a funnel can be attached at the top of the water tank in order to catch and store rainwater. Water will be accessible from a tap at the base of the tank.

Which Nike Grind materials will your idea utilize?

  • Rubber Outsoles
  • Rubber Flashings
  • Rubber Granulate
  • EVA Foam Injection Scraps
  • EVA Foam Flashings
  • EVA Foam Sheets & Blocks
  • EVA Foam Components

How specifically will these materials be incorporated into your solution?

EVA foam will be used to construct the lid and the funnel due to its ability to be injection molded to create unique geometries and its resistance to UV radiation. Rubber will be utilized to construct the bottom and sides of the tank due to its durability and waterproof properties. Our team is currently exploring options for the filter insert. We are not sure the Grind materials have the correct permeability and sterility to safely and effectively filter water. We plan to undergo design of experiment and testing to address this issue during the refinement phase.

Please include a visual (can be either 2D or 3D) representation/prototype of your concept. (required)

What is the current stage of development of your idea?

  • Research & Early Testing

Describe your target market. Who will benefit from your product?

Originally we ideated a portable, backpack-style water filtration system; however, after receiving feedback on our idea from the Engineers Without Borders organization at our university, we learned most communities in developing countries have the means to transport water from their local water source. What they often do not possess is the means to store and filter the water near their home. Thus, we adjusted our idea towards a storage device rather than a transportation method.

How will you scale your idea? Please describe in detail your plan to scale your concept.

How is your idea innovative?

Through the repurposing of EVA and rubber scrap materials, we have produced a cheap and effective method of delivering water storage and filtration capabilities to developing nations.

What inspired this idea?

The NAE proposed “14 Grand Engineering Challenges”, a list of major issues that should ideally be solved in this century. We chose to address the clean water issue. During Mash-Up phase of brainstorming, we merged a backpack and a water filter. This combination developed into our final product.

Tell us about yourself and your team. What is your background and experience?

Our team consists of four university students all exploring design and innovation as Mechanical Engineers: Michael Charonnat, Makenzie Kamei, Andrew Myers, and Amanda Parlog.

Hi Michael,

Great to see you in the Challenge! Could you please provide more content for the submission question, "How specifically will these materials be incorporated into your solution?" How might you begin to turn the raw Nike Grind materials into your final product? What might that process look like step-by-step?

Additionally, to be eligible to advance on to the next phase of the Challenge, please complete the entire submission form with thorough answers.

With the deadline fast-approaching at 5:00 p.m. Pacific Time, please ensure all of your final updates are completed by then.

Excited to learn more!
